Overbooking in Endoscopy: Ensure No-One is Left Behind!

With the growing pressure on physicians to maximize efficiency and enhance the value of clinical practice, overbooking endoscopy schedules appears to hold promise, if implemented strategically, to enhance patient access for endoscopy procedures. Overbooking is a practice that has been routinely utilized by the airline industry to offset losses incurred by passengers not showing for flights, and there is evidence emerging in the medical literature that a similar approach can be utilized in health care. In the context of endoscopy practice, a key aspect of implementing overbooking successfully is the ability to precisely and accurately predict which patients will have a high likelihood of not attending for their procedure, thereby allowing their slots to be double booked while minimizing the likelihood of overburdening the practice with excessive workload. Despite the potential efficiencies that can be realized with overbooking in health care, it remains important not to neglect the needs of those patients who predictably and consistently fail to attend for health-care appointments.

No association between Centers for Medicare and Medicaid services payments and volume of Medicare beneficiaries or per-capita health care costs for each state.

The Centers for Medicare and Medicaid Services recently published data on Medicare payments to physicians for 2012. We investigated regional variations in payments to gastroenterologists and evaluated whether payments correlated with the number of Medicare patients in each state. We found that the mean payment per gastroenterologist in each state ranged from $35,293 in Minnesota to $175,028 in Mississippi. Adjusted per-physician payments ranged from $11 per patient in Hawaii to $62 per patient in Washington, DC. There was no correlation between the mean per-physician payment and the mean number of Medicare patients per physician (r = 0.09), there also was no correlation between the mean per-physician payment and the overall mean per-capita health care costs for each state (r = -0.22). There was a 5.6-fold difference between the states with the lowest and highest adjusted Medicare payments to gastroenterologists. Therefore, the Centers for Medicare and Medicaid Services payments do not appear to be associated with the volume of Medicare beneficiaries or overall per-capita health care costs for each state.

The Inappropriate Prescription of Oral Proton Pump Inhibitors in the Hospital Setting: A Prospective Cross-Sectional Study.

UNLABELLED: Proton pump inhibitors (PPIs) are used to treat upper gastrointestinal tract disorders. Their efficacy and perceived safety have led to widespread prescription. This is not without effect, in terms of adverse events and resource utilization. AIM: To prospectively assess oral PPI prescription in hospitalized patients. METHODS: PPI prescription in consecutive hospitalized patients was assessed. Indication and dose were assessed by patient interview and medical record review. Comparisons with current published prescribing guidelines were made. RESULTS: Four hundred and forty-seven patients were included. 57.5 % were prescribed PPIs. 26.8 % prescriptions were for inappropriate or unclear indications. 68.4 % were on higher doses than guidelines recommended, of which 41.6 % could have undergone dose reduction, and 26.5 % discontinued. In a multivariate analysis, age, gender, and length of stay had no association with PPI prescription. Although aspirin use was appropriately associated with PPI prescription (RR: 1.8, 95 % CI 1.127-3.69; p < 0.05), the PPI was often given at higher than recommended doses (p < 0.001). This may reflect older age and multiple risk factors in this subset. Surgical patients commenced more PPIs and at higher dosages (p < 0.001). Omeprazole and lansoprazole were most often inappropriately prescribed (p < 0.01, p < 0.001, respectively). CONCLUSION: Inappropriate PPI therapy is still a problem in hospitals, though it appears to be at a lower level compared with previous studies. Awareness of evidence-based guidelines and targeted medicine reconciliation strategies are essential for cost-effective and safe use of these medications.

Pricing practices of gastroenterologists in New York.

There is growing awareness of the price disparities for equivalent services in healthcare. We aimed to characterize regional variations in fees charged by gastroenterologists in Manhattan, NY. All private practice gastroenterologists in Manhattan were contacted and asked what they charge fee-paying patients for initial consultations for nonspecific gastrointestinal symptoms. Cost information was obtained from 89 offices, and practices were classified on the basis of location in Manhattan. We observed significant regional variation; gastroenterologists on the Upper East Side (1.20-fold the overall mean) charged more than twice as those on the Upper West Side (0.58-fold the mean) and 50% more than gastroenterologists in South Manhattan (0.76-fold the mean). The coefficient of variation was 46%; the most expensive gastroenterologist charged 14-fold more than the least expensive. We provide evidence for significant regional variation in prices for medical services. Future studies are needed to characterize regional price variations in other aspects of healthcare.

Elevated cord levels of ustekinumab following its use in the treatment of Crohn's disease in pregnancy.

Ustekinumab (USK) was used in the treatment of two pregnant patients with Crohn's disease. It was given in the third trimester and restarted postnatally for both women. One woman remained on USK and in remission throughout pregnancy. The second woman, took a treatment break, flared, and then had remission induced with reintroduction of USK. Both women delivered healthy term infants. The interval from last dose to birth was 11 and 8 weeks respectively. Interestingly, USK levels in cord blood was observed in higher concentrations than in the maternal serum taken in third trimester. While no adverse effect in infants has been observed, clinicians should remain aware of fetal transfer when using USK in pregnancy. An evaluation of risk and benefit may favour continuing USK in pregnancy in patients with refractory disease.

Band ligation of gastric antral vascular ectasia is a safe and effective endoscopic treatment.

BACKGROUND AND AIM: Gastric antral vascular ectasia (GAVE) or 'watermelon stomach' is a rare and often misdiagnosed cause of occult upper gastrointestinal bleeding. Treatment includes conservative measures such as transfusion and endoscopic therapy. A recent report suggests that endoscopic band ligation (EBL) offers an effective alternative treatment. The aim of the present study is to demonstrate our experiences with this novel technique, and to compare argon plasma coagulation (APC) with EBL in terms of safety and efficacy. METHODS: A retrospective analysis of all endoscopies with a diagnosis of GAVE was carried out between 2004 and 2010. Case records were examined for information pertaining to the number of procedures carried out, mean blood transfusions, mean hemoglobin, and complications. RESULTS: A total of 23 cases of GAVE were treated. The mean age was 73.9 (55-89) years. Female to male ratio was 17:6 and mean follow up was 26 months. Eight patients were treated with EBL with a mean number of treatments of 2.5 (1-5). This resulted in a statistically significant improvement in the endoscopic appearance and a trend towards fewer transfusions. Of the eight patients treated with EBL, six (75%) patients had previously failed APC treatment despite having a mean of 4.7 sessions. Band ligation was not associated with any short- or medium-term complications. The 15 patients who had APC alone had a mean of four (1-11) treatments. Only seven (46.7%) of these patients had any endoscopic improvement with a mean of four sessions. CONCLUSIONS: EBL represents a safe and effective treatment for GAVE.

Time of day variation in polyp detection rate for colonoscopies performed on a 3-hour shift schedule.

BACKGROUND: Recent research suggests that the colonoscopy polyp detection rate (PDR) varies by time of day, possibly because of endoscopist fatigue. Mayo Clinic Rochester (MCR) schedules colonoscopies on 3-hour shifts, which should minimize fatigue. OBJECTIVE: To examine PDR variation with the MCR shift schedule. DESIGN: Retrospective cohort. SETTING: Outpatient tertiary-care center. PATIENTS: This study involved completed outpatient colonoscopies in 2008. Procedures were excluded for lack of withdrawal time stamps, indications other than average-risk screening, inadequate bowel preparation, fellow participation, or performance by endoscopists with a low number of endoscopies performed. INTERVENTION: None. MAIN OUTCOME MEASUREMENTS: PDR (colonoscopies with ≥1 polyp divided by total number of colonoscopies) by shift of day. RESULTS: We analyzed 3846 colonoscopies. PDR varied significantly by shift (P = .008) on univariate analysis; results for shifts 1 and 3 were similar (39.0% vs 38.7%, respectively) whereas shift 2 had the highest PDR (44.7%). Mean withdrawal times were stable (P = .92). PDR also varied significantly (P < .0001) by month of year on univariate analysis. On multivariate analysis, patient age (P < .0001), patient gender (P < .0001), endoscopist mean withdrawal time (P < .0001), month of year (P = .0002), endoscopist experience (P = .04), and shift of day (P = .048) significantly predicted PDR. LIMITATIONS: Retrospective study. CONCLUSION: MCR's 3-hour shift schedule does not show a decrease in PDR as the day progresses, as seen in other recent studies. Intervention trials at other institutions could determine whether alterations in shift length lead to PDR improvements.

Application of a conversion factor to estimate the adenoma detection rate from the polyp detection rate.

BACKGROUND: The adenoma detection rate (ADR) is a quality benchmark for colonoscopy. Many practices find it difficult to determine the ADR because it requires a combination of endoscopic and histologic findings. It may be possible to apply a conversion factor to estimate the ADR from the polyp detection rate (PDR). OBJECTIVE: To create a conversion factor that can be used to accurately estimate the ADR from the PDR. DESIGN: This was a retrospective study of colonoscopies performed by board-certified gastroenterologists to determine the average adenoma to polyp detection rate quotient (APDRQ) for all endoscopists, individually and as a group. SETTING: Academic group practice. INTERVENTION: The group average APDRQ was used as a conversion factor for the endoscopist's PDR to estimate the ADR. MAIN OUTCOME MEASUREMENTS: The strength of the relationship between the estimated ADR and the actual ADR determined by Pearson's correlation coefficient. RESULTS: A total of 3367 colonoscopies performed by 20 staff gastroenterologists were included. The average ADR for all indications, all patient age groups, and both sexes was 0.17 (range 0.09-0.27, standard deviation 0.05). The average APDRQ was 0.64 (range 0.46-1.00, standard deviation 0.13). The correlation between the estimated ADR and the actual ADR was 0.85 (95% CI, 0.65-0.93, P = .000001). LIMITATIONS: Retrospective study in 1 practice setting with all patient types. CONCLUSIONS: The use of a conversion factor can accurately estimate the ADR from the PDR. Further study is needed to determine whether such a conversion factor can be applied to different practice settings and patient groups.

Prospective controlled assessment of impact of feedback on gastroenterology trainees in outpatient practice.

BACKGROUND AND AIMS: Previous studies have demonstrated the value of systematic feedback in enhancing endoscopic procedure performance. It remains unknown whether feedback may play a role in modifying physician performance in outpatient practice. This study aimed to assess the impact of systematic feedback on duration of office visits of gastroenterology (GI) trainees in outpatient practice. METHODS: Patients attending a GI outpatient department in an academic medical center were prospectively followed over 4 months. The duration of office visits for consecutive patients seen by five GI fellows of similar experience level were recorded for 2 months (pre-feedback); confidential feedback was then provided to each fellow on a weekly basis for 2 months detailing their individual consultation times and the comparative, anonymous times of the other fellows (post-feedback). RESULTS: Over the course of the study, 1,647 outpatients were seen by five GI fellows. Pre-feedback consultation durations differed significantly with one fellow taking 2.5 times longer than their colleague. Following feedback, times shortened significantly for all fellows, with the greatest impact observed in those trainees taking longer at baseline. There were no significant differences in satisfaction levels among patients seen by each trainee. CONCLUSIONS: There was a wide disparity in the consultation times among GI fellows. Systematic feedback shortened times among all trainees and enhanced uniformity by having the greatest impact among those fellows taking longer at baseline. Routine provision of feedback may be valuable in enhancing uniformity of outpatient practice although clinicians should ensure that shortening consultation visits does not compromise quality of patient care. Future larger studies of feedback in this setting will be enhanced by incorporating objective measures of quality of care and patient satisfaction.

A novel value-based scoring system for endoscopic ultrasound-guided drainage of pancreatic fluid collections: a single-centre comparative study of plastic and lumen-apposing metal stents (NOVA study).

OBJECTIVE: Healthcare resources are finite. Value in healthcare can be defined as patient health outcomes achieved per monetary unit spent. Attempts have been made to quantify the value of luminal endoscopy, but there is little in the medical literature describing the value of the complex therapeutic endoscopic activity. This study aimed to characterise the value of endoscopic ultrasound (EUS)-guided drainage of pancreatic fluid collections (PFCs) with either plastic or lumen-apposing metal stents (LAMSs). METHODS: This is a single-centre, retrospective-prospective comparative study of 39 patients, who underwent EUS-guided PFC drainage between 2009 and 2018. Procedure value was calculated using the formula Q/(T/C), where Q is the quality of procedure adjusted for complications, T procedure duration and C is the complexity adjustment. Quality and complexity were estimated on a 1-4 Likert scale based on the American Society for Gastrointestinal Endoscopy criteria. Time (in minutes) was recorded from the patient entering and leaving the procedure room. Endoscopy time calculated from procedure time was considered a surrogate marker of cost as individual components of procedure cost were not itemized. RESULTS: Of 39 identified patients who underwent EUS-guided PFC drainage, 11 received double pigtail plastic stents (DPPSs) and 28 received LAMSs. The two groups were comparable in age, gender and aetiology. Nearly 40% of the LAMS interventions were considered high value but only 11% of the plastic stent interventions achieved the same. The difference predominantly was due to a higher rate of complications and longer procedure time. CONCLUSION: In this single-centre study, EUS-guided PFC drainage using LAMS was found to be a higher value procedure compared to the use of DPPS.

Co-prescription of gastro-protectants in hospitalized patients: an analysis of what we do and what we think we do.

BACKGROUND: Proton pump inhibitors (PPIs) reduce the risk of upper gastrointestinal hemorrhage (UGIH) associated with the use of many medications. GOALS: To examine how clinicians perceive such risk and whether PPI co-prescribing is based on an accurate assessment. STUDY METHODS: Clinicians in a single teaching hospital were asked to estimate risk of UGIH and comment on PPI co-prescription in hypothetical patients. Records of 160 hospital in-patients (median age; 74 y) were then reviewed to examine PPI prescribing and risk factors for UGIH. RESULTS: In general, clinicians estimated UGIH risk accurately and reported low thresholds for PPI co-prescription. Prescribing records showed regular PPI use increased between admission and discharge of patients from 61/160 (38%) to 93/160 (58%). Ten percent had a prior history of peptic ulcer disease. Proton pump inhibitor prescription was significantly associated with the use of aspirin and clopidogrel. Half of the patients with multiple risk factors for UGIH on admission and almost a third at discharge were not co-prescribed a PPI. CONCLUSIONS: Clinicians generally estimate correctly the risk of UGIH and report a low threshold for prescribing gastro-protection. Despite this, prescribing practice does not consistently take account of relative risk of UGIH. Targeted PPI co-prescribing on the basis of risk factors would lead to more rational PPI use.

Economic impact of prescreening on gastroenterology outpatient clinic practice.

BACKGROUND: Outpatient clinic activity represents a major workload for clinicians. Unnecessary outpatient visits place a strain on service provision, resulting in unnecessary delays for more urgent cases. GOALS: We sought to determine both the impact and economic benefit of employing phone follow-up and physician assistant (PA) triage systems on attendances at a gastroenterology outpatient department. STUDY: We performed a retrospective chart review of all patients attending a gastroenterology outpatient clinic over a 2-week period. Patients were categorized into new or follow-up attendees and the follow-up patients were further subcategorized into 1 of 4 groups: (1) those attending to receive results of investigations requiring no further treatment (group A); (2) those attending to receive results of investigations requiring further treatment (group B); (3) those attending with a chronic gastrointestinal disease requiring no active change in management (group C); (4) those attending with a chronic gastrointestinal disease requiring active change in management (group D). It was assumed that patients in group A could be managed by phone follow-up in place of clinic attendance and patients in group C could be triaged to see a PA. RESULTS: Out of a total of 329 outpatient attendees, 40 (12%) required no active intervention (group A) and would have been suitable for phone follow-up. A further 58 (18%) had stable disease, requiring no change in management and hence, could have been triaged to see a PA. Implementation of phone follow-up and patient review by PA could reduce salary expenses of outpatient practice by 17%. CONCLUSIONS: Our findings support routine prescreening of outpatient attendees to enhance the efficiency of gastroenterology outpatient practice.

Efficacy and safety of colonic stenting for malignant disease in the elderly.

BACKGROUND: Self-expandable metal stents (SEMS) are an accepted palliation for malignant colorectal obstruction. Outcomes of stent insertion solely in older patients are unknown. OBJECTIVE: To compare outcomes of SEMS insertion for malignant colorectal disease, in older versus younger patients. METHODS: Forty-three patients were retrospectively identified as having undergone SEMS insertion for obstructing colorectal cancer. Of these, 24 were > or = 70 years of age (older patient group) and 19 were <70 years of age (younger patient group). RESULTS: There was no significant difference in successful SEMS insertion between the groups (88% in older versus 100% in younger patients, p > 0.05). Furthermore, the complication rate was similar in both groups (12.5% versus 26%, p > 0.10). There was no difference in median survival (113 days versus 135 days, p > 0.09). CONCLUSION: Colorectal stenting for malignant disease in older patients is both safe and effective with comparative success and complication rates to a younger population.

Resource-intensive endoscopy: revenue source or cash drain?

BACKGROUND: Recent research has demonstrated that resource-intensive endoscopic procedures are not financially viable if performed without the need for further clinical care. OBJECTIVE: To determine whether the net income from downstream clinical activities makes resource-intensive endoscopy a financially viable activity. DESIGN: Retrospective database review. SETTING: Tertiary-referral medical center. PATIENTS: Patients whose initial contacts with the medical center were as outpatients who underwent EUS, EMR, or ERCP in 2004. MAIN OUTCOME MEASUREMENTS: Hospital charges, the cost of providing services, revenue, and net income from all services provided through June 2006. RESULTS: A total of 120 patients were reviewed whose initial procedure was EUS (48), ERCP (53), or EMR (19). Although income was lost by performing the endoscopic procedures, revenue was generated by the subsequent clinical care derived from EUS (mean $7093 per patient, standard deviation [SD] $23,686, range $12,316-$117,984 per patient); a loss of revenue was incurred in the clinical care of both patients who underwent ERCP (mean -$5028 per patient, SD $12,565, range -$33,648-$47,481) and patients who underwent EMR (mean -$931 per patient, SD $6515, range -$11,245-$12,196). The most lucrative activity arising from initial endoscopic referral was surgery. Revenue was lost for these procedures in Medicare patients compared with non-Medicare patients. LIMITATION: Indirect costs are institution specific and may not be generalizable to other centers. CONCLUSIONS: EUS is the most remunerative resource-intensive endoscopic procedure. Centralizing these resource-intensive procedures into multispecialty practice sites that provide surgical and oncologic care allows downstream revenue from patient treatment to offset procedural losses. Even taking account of downstream revenues, performing these procedures on Medicare patients is not financially viable. Any future cuts in Medicare physician payment rates will further increase this Medicare/non-Medicare reimbursement imbalance and likely have consequences on the performance of these procedures.
